The following tables are used in Mario Kart DS to determine the probability of receiving an item when an Item Box is opened. Even though the karts influence the probability of obtaining each item through their Items statistics, only the tables for one case are stored in the game's files; this case presumably refers to the use of the Standard karts, that have an Items statistics of 66. The probability is coded as percentage multiplied by two. The distributions are presented in the order used in the code.
In the races, the item probability distributions are chosen depending on the rank of the driver when the Item Box is opened.
